The ocean covers two thirds of the planet and provides half of the oxygen and 20% of the protein for the world's population. However, ocean pollution from human activities is causing problems like ocean acidification. Ocean acidification occurs as the ocean absorbs 25% of the carbon dioxide emitted, which causes the pH of the ocean to decrease as carbon dioxide dissolves in seawater. This chemical change affects over 25% of marine species by decreasing the carbonate ions that many shellfish and corals use to build their shells, putting them at risk of dissolving. To slow ocean acidification and its impacts, carbon dioxide emissions must be reduced.
